Abstract: A user equipment is connected to a master node associated with a master cell group (MCG) and connected to a secondary node associated with a secondary cell group (SCG) using dual connectivity. The user equipment comprises: a controller having a packet data convergence protocol (PDCP) entity associated with a split bearer, a primary radio link control (RLC) entity associated with the PDCP entity, and a secondary RLC entity associated with the PDCP entity; and a receiver configured to receive, from the master node, an RRC message including information for configuring an ID of a cell group associated with the primary RLC entity as an ID of the MCG in a case where the SCG is deactivated. The PDCP entity outputs a PDCP protocol data unit (PDU) to the primary RLC entity in a case where a total volume of a PDCP data volume and an RLC data volume for which initial transmission is suspended is smaller than a threshold.

Abstract: A terminal includes: a receiving unit which receives a discontinuous reception parameter for a radio resource control (RRC) idle state and a discontinuous reception parameter for an RRC inactive state; and a control unit which controls a discontinuous reception operation in the RRC inactive state in accordance with the discontinuous reception parameter for the RRC idle state instead of the discontinuous reception parameter for the RRC inactive state.

Abstract: A communication apparatus configured to communicate with a plurality of networks by using a plurality of subscriber identity modules comprises a communicator and a controller. The communicator is configured to receive, from a network included in the plurality of networks, first information for setting a value of a timer relating to transition of a radio resource management (RRC) connected state, and transmit, to the network, second information to be used to indicate an RRC state transitioning from the RRC connected state. The second information can indicate an RRC inactive state as the RRC state. The controller is configured to start the timer on the basis of transmission of the second information, and cause the RRC state to transition to an RRC idle state on the basis of expiration of the timer.

Abstract: A terminal includes: a receiving unit which receives, from a core network device, an identifier of a subgroup of a paging occasion to which the terminal belongs, and which receives, from a base station, system information including information for indicating a total number of subgroups of the paging occasion and information for indicating a number of paging occasions corresponding to one Paging Early Indication (PEI) monitoring occasion; and a control unit which performs monitoring of a physical downlink control channel (PDCCH) for first downlink control information (DCI) including a field of a PEI in the PEI monitoring occasion, wherein the control unit performs monitoring of a PDCCH for second DCI in the paging occasion in a case where a value of the PEI indicates the subgroup of the paging occasion to which the terminal belongs; and performs no monitoring of the PDCCH for the second DCI in the paging occasion in a case where the PEI is not detected, or a value of the PEI does not indicate the subgroup of the paging occasion to which the terminal belongs, and a number of bits for the field of the PEI is determined based on the information for indicating the total number of subgroups of the paging occasion and the information for indicating the number of paging occasions corresponding to the one PEI monitoring occasion.
